The National Popular Vote Compact Just Signed by Abigail Spanberger is an Unconstitutional Timebomb

On April 14, 2026, Virginia Governor Abigail Spanberger signed House Bill 965 into law, making the Commonwealth the 19th jurisdiction to join the National Popular Vote Interstate Compact. The compact now commands 222 electoral votes and requires 48 more to activate. When it activates, each member state will be obligated to award its electors, by statute, to the candidate who wins the national popular vote, regardless of how that state’s own voters actually voted. Virginians, in other words, may cast ballots for one candidate in November and watch their 13 electoral votes delivered in December to the other. The compact does not merely change the rules of presidential elections. It proposes to change what a state’s vote means, and it proposes to do so without amending the Constitution.

Begin with a simple comparison. Suppose 19 states passed statutes declaring that, upon reaching a threshold, each would send its two senators to Washington based on the national popular vote for senator rather than the vote inside its own borders. Every lawyer in the country would recognize this as absurd on its face. Article I, Section 3 vests senatorial selection in the states as states, and the 17th Amendment modified that selection by formal constitutional amendment, ratified by 3/4 of state legislatures. Nobody tried to reach the same result by interstate compact, because everybody understood that restructuring the constitutional electorate for a federal office is the kind of change the Constitution deliberately makes hard. The National Popular Vote Interstate Compact attempts to do for the presidency what the 17th Amendment’s drafters would not even have considered attempting for the Senate. That is the beginning of the problem, not the end of it.

The compact’s defenders will object that Article II, Section 1 gives each state legislature plenary power to direct the manner of appointing presidential electors, and that the compact is merely an exercise of that power. This is the argument’s most serious form, and it deserves a serious answer. The plenary power of a state legislature to appoint electors is the power to choose its own electors, not the power to outsource that choice to a nationwide tabulation that aggregates 51 different election systems operating under 51 different sets of rules. A Virginia statute that directs electors according to the vote of Virginians is an exercise of Article II authority. A Virginia statute that directs electors according to the certified returns of California, Texas, and every other jurisdiction is something different. It is an agreement among states to pool their Article II authority into a nationwide mechanism, and the Constitution has a specific clause for that.

That clause is Article I, Section 10, which provides that no state shall “enter into any Agreement or Compact with another State” without the consent of Congress. The Supreme Court in Virginia v. Tennessee and in US Steel Corp. v. Multistate Tax Commission held that not every interstate agreement requires consent, only those that alter the horizontal balance of power among the states or the vertical balance between the states and the federal government. The compact’s defenders rely on this narrowing principle. But the narrowing principle cuts decisively against them here, not for them. The Multistate Tax Commission compact concerned state tax administration. The interstate compacts the Court has upheld concern water rights, port authorities, bridge tolls, and the management of shared natural resources. None of them determined who would occupy the presidency of the United States. If any interstate agreement alters the horizontal balance of power among the states, an agreement that transfers control of the presidency from a state-based aggregation to a national plurality is that agreement. Princeton Legal Journal’s analysis put the point cleanly: the compact is “a compact of a political nature that encroaches upon the power of non-member states, does not allow for signatories to withdraw at will, and gives its member states far more power than they would have had in its absence.”

Here the argument gets sharper, and worse for the compact. Even if the Compact Clause requires congressional consent, Congress may lack the power to give it. Professor Ian Drake of Montclair State University has argued that Article I, Section 8 contains no enumerated power authorizing Congress to restructure the Electoral College, and that consent to a compact which functionally restructures the Electoral College is therefore beyond congressional reach. Consider the logic carefully. Article II, Section 1 assigns the manner of appointing electors to the state legislatures. Congress is not in that sentence. If Congress cannot itself redesign the Electoral College, it cannot bless by consent a compact that redesigns the Electoral College from the outside. The compact is caught in a vise. Without consent, it violates the Compact Clause. With consent, the consent itself is constitutionally infirm. This is not a technicality. It is the structural consequence of a mechanism that attempts to accomplish through ordinary legislation what Article V exists to accomplish through supermajority ratification.

A third legal vulnerability arises from the 14th Amendment. The Supreme Court in Bush v. Gore held that once a state grants its citizens the right to vote for president, the Equal Protection Clause requires that votes be given equal weight. The compact aggregates ballots cast in 51 jurisdictions operating under materially different voter eligibility standards, identification requirements, ballot design rules, provisional ballot procedures, and recount triggers. The resulting national total is not a single election conducted under equal conditions. It is the sum of 51 elections conducted under 51 sets of rules, treated, by the compact’s operative text, as “conclusive” on each member state. A Virginia voter whose ballot is subject to Virginia’s integrity safeguards is given the same numerical weight as a ballot cast in a jurisdiction with same-day registration and no identification requirement. Under Bush v. Gore’s reasoning, this is precisely the kind of unequal treatment of materially different ballots that the 14th Amendment forbids. Harvard Law Review’s analysis concluded that if a close national vote triggered a recount in some states but not others, the resulting patchwork would violate equal protection for the same reason the Florida recount did in 2000.

A fourth objection cuts at the compact’s internal machinery. The compact prohibits member states from withdrawing during the six months preceding the end of a presidential term. Former Federal Election Commission member Hans von Spakovsky has noted that the Multistate Tax Commission compact, on which the Court’s permissive ruling rested, allowed member states to withdraw at any time. The National Popular Vote compact does not. The Supreme Court in McPherson v. Blacker described the state legislature’s authority over the manner of appointing electors as authority that “can neither be taken away nor abdicated.” A compact that binds a future legislature’s Article II judgment during the most consequential period of the election cycle is a compact that asks one legislature to abdicate the plenary authority the Constitution assigns to every successor legislature. The blackout clause is therefore constitutionally suspect, and if it falls, the compact loses the only provision that prevents opportunistic withdrawal in the weeks before a close election. An unenforceable compact governing the presidency is not a feature. It is a legitimacy crisis in waiting.

A fifth vulnerability lies in the Electoral Count Reform Act of 2022, which passed with bipartisan support and which requires governors to certify electors “in accordance with the laws of the State enacted prior to election day.” The compact’s trigger is dynamic. It activates when member states collectively reach 270 electoral votes, and its determination of a winner depends on certified returns from all 50 states and the District of Columbia. In a close national contest, those returns will not all be final when a governor must certify. The statutory certainty that the ECRA was designed to guarantee collides directly with a compact that depends on tallies outside any single state’s control. A governor of a compact state in a disputed national count faces a choice between complying with the ECRA’s state-law-based certification requirement and complying with a compact that has no resolution mechanism for incomplete or contested national returns.

The sixth vulnerability concerns the Voting Rights Act. Section 2 prohibits practices that abridge the right to vote on account of race. In a state where a minority community holds decisive influence under the current winner-take-all system, the compact would dissolve that influence into a national electorate in which the same community’s proportional share is significantly smaller. Whether this constitutes vote dilution under Section 2 is an open question, but it is a question no court has answered, and its answer will not be known until litigation forces it.

Stack these six theories together. The compact may violate the Compact Clause. If it does not, Congress may lack constitutional authority to cure the violation. Its aggregation of 51 election systems into a single national tally raises equal protection concerns that track Bush v. Gore directly. Its withdrawal blackout is in tension with McPherson v. Blacker. Its operation conflicts with the Electoral Count Reform Act’s statutory architecture. Its effects implicate the Voting Rights Act. No interstate compact in American history has ever presented this density of unresolved constitutional and statutory defects, and the Congressional Research Service itself has concluded that activation would generate litigation almost certainly reaching the Supreme Court in the compressed interval between election day and the meeting of the Electoral College.

Now consider what that litigation would look like. The current Electoral College has an underappreciated structural virtue: it contains post-election disputes within the borders of the states where they arise. Florida in 2000 was a crisis, but it was a Florida crisis. Under the compact, every close national election becomes an every-state crisis. Recounts, provisional ballot disputes, signature-match challenges, and ballot-curing fights become nationally strategic wherever additional votes might be found. The computer scientists Ronald Rivest and Philip Stark have argued that the compact undermines election integrity precisely because no national audit architecture exists to verify a national tally, and member states must accept other states’ returns as conclusive even when those returns are themselves contested. The Electoral College’s quiet gift to the republic is that it localizes error, fraud, and litigation. The compact removes that firebreak.

This brings the argument to its proper conclusion, and to the only institution that can resolve it before the compact reaches 270. Congress has both a constitutional role and a political duty here. The Compact Clause gives Congress the authority to withhold consent from interstate agreements that alter the balance of power among the states. A joint resolution declaring that the National Popular Vote Interstate Compact lacks congressional consent, combined with a finding that the compact alters the horizontal balance of power among the states and encroaches on federal supremacy, would force the question into court on favorable procedural terrain rather than in the chaos following a contested election. Congress could go further. It could pass a statute, grounded in its authority over the time of choosing electors and the ECRA’s certification framework, clarifying that electors must be appointed based on each state’s own returns. It could hold hearings that put the compact’s drafters and legal architects under oath to explain how the mechanism handles a nationwide recount, a contested tally, or a withdrawing member state in the weeks before certification. It could do all of this before the compact activates, while the questions are academic and the stakes are still governable.

The alternative is to wait. Wait for the compact to reach 270. Wait for a close election. Wait for a state to be forced to award its electors to a candidate its own voters rejected. Wait for the lawsuits, the emergency applications, the competing certifications, and the legitimacy crisis that will follow. The Founders built Article V because they understood that fundamental changes to the constitutional order must rest on broad and deliberate consent, not on the statutory initiative of a coalition of states acting alone. The compact is an attempt to bypass that architecture. Congress has the authority to stop it. The only question is whether Congress will act while acting is still cheap, or wait until acting is both expensive and late.
